RD Sharma Solutions for Class 10 Mathematics Chapter 11: Constructions

Students learned how to construct line segments, bisect angles, perpendiculars to line segments, using a ruler and a compass in the previous academic session. Chapter 11- Constructions is a continuation of these topics at a slightly advanced level.

This chapter deals with the construction of a line segment and then dividing it in a specific ratio. This is achieved by the use of a compass, a divider, a ruler and a compass.

Chapter 11- Constructions also teach the methods to construct a triangle similar to a given triangle based on the scale factor.

Here, the scale factor refers to the ratio of the triangle sides to be constructed with the corresponding sides of the triangle provided to us.

Apart from straight lines and triangles, this chapter also deals with the construction of Tangents to a circle from a specific point present outside the given circle.

Similar constructions have been explained throughout the chapter with varying angles and magnitudes to provide thorough revision and practice. These basic construction methods are essential for the chapters related to geometry that follows.

The previous years' exam patterns suggest that this chapter holds a considerable marks weightage. Thus, apart from future references, students need to be thorough with the topics mentioned in this chapter from an examination point of view.
